Troubleshooting the buttons

About this task

The phone should play a tone if you press the volume buttons while the phone is idle.


  1. Tap the Phone icon and then tap some digits on the keypad.

    If you hear the DTMF tones from the digits, there may be a problem with the hardware. Continue to the next step.
